Recommended Cutting Parameters
Optimize your CNC metal drilling performance with these reference values:
- Cutting Speed (Vc): 110 - 180 m/min (Adjust based on material).
- Feed Rate (f): 0.06 - 0.12 mm/rev.
- Coolant Requirement: Internal High-Pressure Coolant is mandatory for 5D depth to clear chips effectively.
WC Type U-Drill: Pros & Cons
- Uses WCMX / WCMT inserts with 4 cutting edges (Cost-effective).
- Better stability on uneven entry surfaces.
- Smooth chip breaking on low-carbon steels.
- Higher torque requirements than SP series.
- Sensitivity to spindle alignment in deep 5D holes.
Material & Flute Geometry
Constructed from high-strength alloy steel with specialized anti-vibration heat treatment. The spiral flute geometry is wide-designed for "forced" chip evacuation, preventing chip-packing—the primary cause of tool breakage in deep hole drilling. This WC06 insert holder is nickel-plated for superior corrosion resistance and prolonged tool body life.
Pro-Tip: Choosing Drill Depth (2D to 5D)
Selecting the correct L/D ratio is critical for CNC tooling performance:
- 2D/3D: Maximum rigidity. Best for high-speed shallow holes.
- 4D: The universal standard for general purpose machining.
- 5D (This Model): Specialized deep-hole drill. It requires high-pressure internal coolant and precise spindle alignment to ensure straightness and tool longevity.
